language/speech problems?

hmmm... how do i explain it
Well i have trouble speaking quickly, fluently and intelligently and in expressing myself
ill give an example :
I was asked by a friend to tell anything about my project on which i had done a LOT of research and stuff. But i couldnt remember most of the things fast enough. And what I remembered I couldnt find the correct words to describe, say the technical terms and form sentences fast enough like a normal person
here's another one:
my teacher asked a question. i knew the answer was alpha particle. i could visualise the alpha particle the instant i figured it out but had trouble saying it quickly. in frustration what came out of my mouth was 'boson'.
this stuff happens to me a lot everyday and has been happening since my childhood
my parents and siblings also seem to show this although at different levels
wheather english or my tongue i am often told that "you could have said it like this faster" or "use more synonyms" and talking to anyone feels like pushing a giant boulder and this has made me quite socially anxious
i did a lot of research and the closest thing i found out was anomic aphasia but i doubt i have it after seeing a couple of videos and as it shouldn't be heredetiary (right? )
my psychiatrist didnt say anything on it and i have been taking anti-depressant and adhd tablt since a month
any ideas what this could be?

and does anyone remember the correct word for .. uh.. talking more um like a pro?(like more nevermind)
i dont think 'intelligently' is the right word

I've never had fluent speech either but it sounds like when you try to talk the completely incorrect terms come out. I've always focused on writing since if I take my time I can usually do a lot better with that. I'm not sure how to help, sorry, but you seem to do fine with writing too.

Hello blind archer,

You said that you are often told that you could have said something faster or you should use more synonyms, you know, that puts huge pressure on you. That would make you super aware and anxious to start off with. If you are prone to anxiety anyway, then you are likely to trip over your words and be afraid to speak for fear of being picked up on it.

There can be other reasons of course, psychosis for example can cause huge confusion and what we call 'word salad' where words are totally mixed up, dementia can do the same, depression can cause a dumbing down and slowness but anxiety seems the most likely reason. Of course I will urge you to get checked out with your doctor incase it is a brain tumor or something else physical causing the issue.

my speech never seems intellectually complex enough for my age
i try and i myself can clearly know when it is happening but cant stop it

I tried so hard to fix myself, all the things I didn't do well, when I was younger. As I got older I realize now there isn't time. So I accept that I can't do some things well (many things!) and focus on whatever I'm able to do. It's very hard. Not trying to sound like a know it all because I know very little, but I want you to love yourself as you are and not internalize everyone saying you're not good at something. What are they not good at? No one is good at everything except maybe fictional characters.
